JOHN BROUGHTON, OF BROOKLYN, ASSIGNOR TO WILLIAM JOHN GRIF- FITHS, OF GREEN POINT, NEW YORK.

IMPROVEME NT IN FASTENERS FOR MEETING-RAILS OF SASHES.

Specification forming part of Letters Patent N0. 204,794, dated June 11, 1878; application filed May 22, 1878.

To all whom it. may concern: Be it known that I, JOHN BROUGHTON, of Brooklyn, in the county of Kings and State of New York, have invented a new and useful Improvement in Sash-Fasteners, which improvement is fully set forth in the following specification, reference being had to the accompanying drawing, in which- I Figure 1 is a top or plan view of the sashfastener. Fig. 2 is a vertical central section in the plane a a, Fig. 1. Fig. 3 is an inverted plan view of the latch. Fig. 4 is a detached view of the handle.

Similar letters indicate corresponding parts.

The object of this invention is to furnish a neat, cheap, and efficient sash-fastener, which will prevent the sashes from being separated in any direction, and which is easily operated and not liable to get out of order; and it consists in a novel construction and arrangement of parts, hereinafter particularly described, and definitely pointed out in the claims.

In the drawing, the letters A B designate two meeting-rails of a window-sash. To the rail B is fastened the frame O. The latch D revolves about a standard rising from said frame 0, being held thereon by a screw, a, Fig. 2. Said frame 0 is provided with a U- shaped rim, d 0?. (Best seen in Fig. 1.) A spring, I) b, rests in depressions or recesses formed in said U-shaped rim. This spring b 1) acts on the cam-shaped hub c c, Fig. 3, of the latch D, causing it to stay either in the positions shown in Figs. 1 and 2 when the latch closes the window, orin a position so that the window can be opened--that is, when the latch has made a quarter of a revolution.

To the rail A is fastened a frame, E. From this frame E rises a concave covered flange, f f, the top of which is removed in Fig. 1. The top of this flange f f is provided with a lip, (seen in Fig. 2), which lip engages with a depression, 0, in the latch D when the latch is turned so as to close the window. The

handle F of the latch D is provided with two recesses, g g, and a lip, h, which engages with two lips, i i, and a recess, k, in the latch D, and so a hinge-joint is formed without using a pintle. This arrangement allows the handle F to fall into a recess, 1, in the rim m of the supporting-frame O O, Fig. 1, so as to retain the latch D in its locking position, and to raise the handle out of said recess if the latch is to be turned.

A great advantage of this construction is that the different parts of the sash-fastener can be cast and then put together rapidly and securely.

What I claim as new, and desire to secure.

by Letters Patent, isv 1. The combination, in a sash-fastener, of a supporting-frame provided with a recess, 1, in its rim, a handle, F, adapted to engage with said recess 1, and provided with a depression or depressions, g, and a revolving latch provided with a lip or lips, 2', adapted to engage with the depressions of the handle and to form a hinge-joint without a pintle, substantially as and for the purpose set forth.

2. The combination, with the handle F, constructed substantially as described, of the oscillating latch D having the cam-shaped hub c and depression 0, straight flat spring I),

all upon the top of the lower sash-frame, and the concave coveredflange f, provided with a downward-projecting lip for engaging in the depression of the latch, whereby said latch is held securely in its locking position and the two sash-frames are prevented from being separated in any direction, as set forth.

In testimony that I claim the foregoing I have hereunto set my hand and seal this 2d day of April, 1878.
